You live, you learn—even if you’re a larva and especially if there’s a little shock involved.

Dingoes can wreak havoc on Australia’s sheep population, so the canines have been fenced off from a large section of the country. But new research suggests that excluding dingoes can lead to a population boom in their preferred prey, kangaroos, that can change the plant composition of the landscape and even the soil chemistry. The finding is the latest addition in a long and contentious dispute about the effects of dingoes on Australia’s ecosystems.
